Mississippian fossils are abundant in portions of the Midwest and South and include vast beds of limestone and marble.
Explanation:
For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
Answer:
any time a source of energy is obtain using natural means, the 10 % rule will apply. 10 % rule means when energy is passed in an ecosystem from one trophic level to next, only 10% of the energy will be passed on. A trophic level is the position of organism in the food chain.
So Quaternary consumers are at the top position in the food chain, they will receive less energy from the food as compared to the primary consumers which are at the bottom of the food chain. so when getting less food and less energy, Because of this, the populations of Quaternary consumers are usually the smallest out of the populations in the food chain.

Able to find more food means more likely to survive - survival of the fittest i.e. natural selection.</span>
